Patent number: 7842823Abstract: The present invention provides a novel class of fluorogenic probes for reactive oxygen species. Exemplary probes of the invention utilize a boronate deprotection mechanism to provide high selectivity and optical dynamic range for detecting H2O2 in aqueous solution over similar reactive oxygen species (ROS) including superoxide, nitric oxide, tert-butyl hydroperoxide, and hydroxyl radical; Peroxyresorufin-1 (PR1), Peroxyfluor-1 (PF1), and Peroxyxanthone-1 (PX1) are first-generation probes that respond to H2O2 by an increase in red, green, and blue fluorescence, respectively. The boronate dyes are cell-permeable and can detect micromolar changes in H2O2 concentrations in living cells, including hippocampal neurons, using confocal and two-photon microscopy. The unique combination of ROS selectivity, membrane permeability, and a range of available excitation/emission colors establishes the potential value of PR1, PF1, PX1, and related probes for interrogating the physiology and pathology of cellular H2O2.Type: GrantFiled: October 27, 2006Date of Patent: November 30, 2010Assignee: The Regents of the University of CaliforniaInventor: Christopher J.

Publication number: 20100168404Abstract: The present invention provides compositions of matter useful as deposition agents for making structures, including thin film structures and hard coatings, on substrates and features of substrates. In an embodiment, for example, the present invention provides metal complexes having one or more diboranamide or diboranaphosphide ligands that are useful as chemical vapor deposition (CVD) and/or atomic layer deposition (ALD) precusors for making thin film structures and coatings. Metal complex CVD precursors are provided that possess volitilities sufficiently high so as to provide dense, smooth and homogenous thin films and coatings.Type: ApplicationFiled: April 9, 2008Publication date: July 1, 2010Applicant: THE BOARD OF TRUSTEES OF THE UNIVERSITY OF ILLINOIInventors: Gregory S. Girolami, Do Young Kim, John R. Abelson, Navneet Kumar, Yu Yang, Scott Daly

Publication number: 20100137249Abstract: The present disclosure encompasses compounds and compositions that are useful as specific AI-2 antagonists for the control of bacterial quorum sensing. Although the AI-2 antagonists according to the present disclosure may not have bactericidal effect, their ability to attenuate virulence, drug resistance, and/or biofilm formation have therapeutic benefits. In addition, the AI-2 antagonists of the present disclosure can also be used as tools to probe bacterial AI-2 functions. The present disclosure also encompasses methods for inhibiting or attenuating microbial virulence, biofilm formation, and drug resistance. The methods are suitable for preventing bacteria from accruing and forming extensive biofilms that may be a health or hygiene hazard or a physical issue, such as in the blockage of water or fuel lines.Type: ApplicationFiled: June 6, 2008Publication date: June 3, 2010Inventors: Binghe Wang, Nanting Ni, Junfeng Wang, Chung-Dar Lu, Han-Ting Chou, Minyong Li, Shilong Zheng, Yunfeng Cheng, Hanjing Peng
